WELL CASING.

Application filed May 4, 1925.

To all whom it may conccm:

Be it known that I, KRIsTEN SONDERBY, a citizen of the United States, residing at Rockford, in the county of Vinnebago and 6 State of Illinois, have invented certain. new

and useful Improvements in ell Casings,

of. which the following is a specification.

The present invention relates to well casings, and more particularly to sectional casm s.

in object of this invention is to provide a well casing which may be moulded or cast in special forms built for that purpose, the sections being locked together when they are placed in position.

Another object of this invention is to provide a well casing which due to the various locking devices cannot be collapsed by the slipping of the earth therearound or from other causes.

A further object of this invention is to provide a device with an enlarged base ring which when inserted in the well opening will permit the various sections to be lowered into position without difiiculty.

A still further object of this invention is to provide a device of this character which has locking members holding the various sections against lateral movement and the locking members may be used as steps for the purpose of descending or ascending the well.

The above and various other objects and advantages of this invention will in part i6 be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings, wherein:

m Fig. 1 is a transverse view taken vertically through substantially the middle of the device and showing in detail the interior construction.

Fig. 2 is a transverse view taken substan- LB tially on the line 22 of Fig. 1 looking downwardly.

Fig. 3 is a transverse view taken through the device on the line 3-3 of Fig. 2.

i6 Fig. 1 is a front elevation of a well casing constructed according to this invention,

part of the casing being cut away to permit illustration of the top of the casing.

Fig. 5 is a perspective view of the base of the well casing.

Serial No. 27,940.

Fig. 6 is a perspective view of one of the sections of the casing.

Fig. 7 is a perspective view of one of the keys or looking members, and

Fig. 8 is a perspective view of one of the key steps.

Referring to the drawings, 10 designates the earth orground in which it is desired to sink the well. An opening 11 is dug in the usual manner, and in this opening the bottom or base ring 12 of the casing is placed. The ring 12 is provided with a flaringbase portion as shown at 13 so that the wall or casing 14. will stand away from or in spaced relation to the walls of the opening 11. WVhile it is realized that in a short time the earth will soon fall against the outer walls of the casing, nevertheless during the process of the construction of the well the earth will stand away long enough to insert the various sections 15 which are placed one upon another until the top of the opening is reached.

The base 12 is provided with a pair of opposing sections 16 which are preferably about one-half the height of the sections 15. The half-sections 16 are secured to the base ring 12 and are preferably cast therewith. In the top of the half-sections 16, and in the top of the base 12 there is provided a tenon 17 which is adapted to fit into a corresponding groove 18 in the bottom of the section 15. At one end of the half sections 16 there is a tenon 19 and at the opposite endthere is provided a groove 20, and the section 15 is also provided with a similar tenon 19 and groove 20 at opposite ends thereof, so that the section 15 may be slid into position, the tenon 19 of section 15 fitting into the groove 20 of the half section 16, and the groove 20 of the section 15 receiving the tenon 19 of the half section 16.

The circumference of the casing is made full keyway is thus formed, and into this opening a key 22 is inserted to lock the sections 15 against lateral or vertical movement.

Vith the provision of two t nons and two grooves in each section and a plurality of half keyways in the ends of the sections 1.3 there is no possibility of the diiierent sections becoming dislodged by the inoienient of the earth surrounding the casing once the keys 2 are placed in position. In alternate keyways 21 there may be inserted, in lieu of the keys 22 whichare flush with the inner and outer walls of the casing, a key step 23, the inner portion of which extends into the well opening. A plurality of rungs 24 may be cast on the inner portion of one series of the sections so as to provide means by which a person may hold himself securely while descending or ascending the interior of the casing.

In order to place the well casing herein disclosed into its proper position I'QQllllQS no unusual degree of skill, and as the various sections are only one-quarter of the circumference of the casing each individual section 15 is not of excessive weight and therefore does not require special apparatus to place it in position. The opening 11 is first'dng in the usual manner, and is (it satficient size to receive the base. ring 12. As the base ring 12 flares out at the bottom the opening 11 will correspondingly be larger than the circumference of the i. ising proper. Having placed the base or bottom ring 12 in position a section 15 is lowered into the opening between the two halt sections 16. This section 15 when in position extends substantially one-halt of its height above the two half sections 16. Proceeding in this manner the opposite quarter tions 15 will lie in the same plane with each other. lVhen the top of the opening 11 is reached two halt-sections 16 are placed in opposite quarter sections of the circumter ence, and thus there is presented a smooth top. Vith the placement of each section 15 the keys 22 are inserted in the keyways 21, and if desired the keysteps 23 may be placed in alternate keyways 21 along one side oi the casing and on the inside thereof in order to provide steps to descend or ascend the well.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of the invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims:
